What does $this actually mean> Codeigniter

Question

Silly question I know,

From all the tutorials they do not explain why they use $this.

Is $this like an object from a base class in Codeigniter?

Any e

Answer 1

$this isn't something from CodeIgniter, but from PHP. $this refers to the current object.

Whenever you create an instance like this:

$something = new SomeClass();

Then $this refers to the instance that is created from SomeClass, in this case $something. Whenever you are in the class itself, you can use $this to refer to this instance. So:

class SomeClass {

  public $stuff = 'Some stuff';

  public function doStuff()
  {
    $this->stuff;
  }

}
